I have used the jolla phone quite some time now. Mainly for basic
activities. Just for making calls, short messages and checking emails.

I want to use it extensively now. In the way that contacts, calendar
appointments, music and photo files, bookmarks etc. gets synchronized
in some way with a laptop or by other means.

The actual questions are:
How the conceptual ecosystem looks like?
What sync ways are mainly integrated by design into the applications of jolla/sailfischOS?
How is the community doing this type of activities?
